The use of polymer matrix composites to repair and strengthen structures in the oil industry has become a common industry practice. The use of these reinforcements extends from covering surfaces with defects, through wall or not, to structural reinforcement. In the last decade, many studies have been done to develop an alternative approach to the strengthening and repairing of pipelines with composite materials. Recently, in 2006, the ISO system of technical standards presented the document technical support "Petroleum, petrochemical and natural gas industries Composite repairs for pipework Qualification, design, installation, testing and inspection" ISO/PDTS 24817. This study aims to develop a repair system using polymer matrix composite materials for repair and reinforcement of piping and pipelines in accordance with ISO 24817:2006. Procedures where developed for the confection of test specimens for mechanical testing, and application of the repair. The system is intended to repair defects such as thickness loss, gouges, and damage through wall or not. In parallel, an entire infrastructure was built for the conception of a laboratory for the study of composite materials at the Laboratory of Adhesion and Adherence. Here are presented the results of the required mechanical tests, the comparison results with theoretical models, and the hydrostatic testing.
